This book introduces Reformed theology by surveying the doctrinal concerns that have shaped its historical development. The book sketches the diversity of the Reformed tradition through the past five centuries even as it highlights the continuity with regard to certain theological emphases. In so doing, it accentuates that Reformed theology is marked by both formal ('the always reforming church') and material ('the Reformed church') interests. Furthermore, it attends to both revisionary and conservative trends within the Reformed tradition.

The book covers eight major theological themes: Word of God, covenant, God and Christ, sin and grace, faith, worship, confessions and authority, and culture and eschatology. It engages a variety of Reformed confessional writings, as well as a number of individual theologians (including Zwingli, Calvin, Bullinger, Bucer, Beza, Owen, Turretin, Edwards, Schleiermacher, Hodge, Shedd, Heppe, Bavinck, Barth, and Niebuhr).
